An affirmative answer to a question on connectivity of p-subgroup posets with irreducible characters

Gang Chen, Wenhua Zhao

Let $p$ be a prime, $e$ a nonnegative integer, and G a finite p-group with $p^{e + 1}$ dividing $∣ G ∣$ . Let I be the intersection of all subgroups of order $p^{e + 1}$ in $G$ . It is pro…

Notes on finite totally $2$ -closed permutation groups

Gang Chen, Qing Ren

Let $N$ be a normal subgroup of a finite group $G$ . For a faithful $N$ -set $Δ$ , applying the university embedding theorem one can construct a faithful $G$ -set $Ω$ . In this short no…

Schur Rings over Z \times Z_3

Gang Chen, Jiawei He

For the direct product $\cZ\times \cZ_3$ of infinite cyclic group $\cZ$ and a cyclic group $\cZ_3$ of order $3$ , the schur rings over it are classified. In particular, all the schu…
